`This invention is directed to an improve#V ment in plows and particularly to a mea-ns `whereby the plowshare and moldboard may y be selectively inclined with respect to theV surface to graduate the introduction of the same into the soil to adepth determined by `therequired depth orthe subsequent sowing.

The primary object of the present inven- -tion is to mount the moldboard and plowlo share for pivotal connection with the plow-"' beam and provide manually'controlled le- `ver mechanism whereby the inclination of the plowshare and moldboardlmay be selectively determined. i5 The invention is illustrated inthe accompanying drawings, in which Figure 1 is an enlarged broken side elevation illustrating the improved invention, the inclinationvof the moldboard and plowshare L 2G being indicated in'dotted lines. 1

`Figure 2 isa side elevation of the plow complete.

The improved plow includes a beam 1,1

handles2 and a wheel 3 which may be of Vdei V sired or conventional form.` Carried by the rear end of the plowbeam 1 1s a skeleton` `frame 4, the rear edge of which is formed to provide a series of teeth 5. The frame i includes a depending leg 6 to which a conventional m-ol'dboard and plowshare 7 is pivotn ally supported at 8. t

An operating lever 9 is pivotally supported on the frame 11 at 10, the pivot 10 be:n ing in substantially vertical alignment with the'pivot`3. The lever 9 Aei'itends'omvarclly and rearwardly 'of the pivot 10, the rear `portion being sutiiciently extended to pro-` `vide a handle 11, the handle grip 12 of which is below the plow handles 2. e Slidablymounted on the extended portion 11 of the lever 9 is a slide 13 having a tooth 14 which will selectively cooperate with any of the teeth 5 of the frame 4. A spring 15 normally holds the slide in teeth engaging position, a finger lever 16fmounted adjacent the grip 12 of thelever 9 being connected by a rod or wire 17 with theslide 13 to withdraw the slide from engagement with the teeth 5 at will. e i i e 59 Links 18 and 19 connect the lever 9 on optermine'd bythe characterofthematerial toA A e t Y unit pivotally mounted on theframe, a man- CSAR Bomms ne LA mi,` on HABANLpUBA posite Asides of and `at'rcelui-distant i `from ythe `pivot`10"with the plowshare 7, l the connejctionfof the links to the plowshare f being on opposite sides of and at substan` tially `equi`distantfpoints from the pivot 8. `55

Obviously, movement of the leverl 9j in one direction or theother on its pivot 10 corre-V spondingly moves the plowshare :froml the horizontal position indicated "in full 4lines in F igurel toa positionfinclined `with respect to 1thehorizontal, onefsuch l "osition being indicated sin1 dotted lines ingurel'. As the slide 13 mayinterlockwith `any of the teeth 5"of the frame, `it'is-apparent that the pljowshare. andimoldboard may be movedto 65 and secured in a'plurality-of differently" inclined positions alt -will,` and thatthe posie tion ofsuch share ormoldboard can be read# ily andconveniently changed; when `desired by simple manipulation ofthe lever 9 in an obvioustnianner'. wf

A hanger strap 20 depends romthehani dles V2fand1ser`ves as `astirrupiifor the lever 9,limiting the operativemovenient ofw'theV lever-infone, direction. The plowshare and 75 moldboardlmay be thus changedin itsc'ut!` ting yinclination and thus enter-the surface to diierently selected depths as may be Udef be later `sowed.` y t n If desired and as preferred, the linklS may be ormedfon its forward edge as; ai" cuttingedge, as indicated at 21V this cuttingf edge -servingito cutroots and the like as the plow advancesf., y

What is claimed to be new is:` :n 1,. A `plow lincluding a beam, a; frame `secured thereto,- a` plowshareand moldboard ually operable lever pivotally mounted on .p the frame, and links connecting the lever and said unit on opposite sides of the respective pivots, the forward link being-y sharpened p Y e to form a cutting edge.

2. A plow including a beam, a frame secured thereto, a .plowshare and moldboard A unit pivotally mounted on the `frame, amanually operable lever pivotally `mounted on the frame, links connecting the lever and said unit on opposite sides of the respective pivots, the front edge of the forward link being sharpened to form a cutting edge, said frame being formed with a plurality of teeth, and a manually controlled dog on the lever for co-operating with the teeth to lock the lever in a plurality of positions.

3. A plow including a standard, a plowshare and moldboard unit pivoted to the standard, an operating lever pivoted to the standard, said latter pivot being in vertical alignment with the pivot of said unit, and substantially parallel links pivoted tothe lever and said unit on opposite sides of the pivots.

4. A plow including a beam, a frame secured thereto and provided at its rear end with teeth, a plowshare and nioldboard unit pivotally mounted to the lower portion of the frame, a manually operable lever pivotally mounted on the frame, the pivots of said unit and lever being in vertical alignment, links pivoted to the lever and unit-on opposite sides of the respective pivots, and means whereby the lever may be secured at a plurality of different positions with re* spect to the frame including a spring actuated dog on the lever cooperating with the teeth on the frame.

5. A plow including a beam, a frame secured thereto, a plowshare and moldboard unit pivotally mounted on the frame, a manually operable lever pivotally mounted on the frame, the pivots of said unit and lever being in vertical alignment, links connecting the lever and said unit on opposite sides of the respective pivots, the front edge of the forward link being sharpened to form a cutting edge, said frame being formed with a plurality of teeth, and a manually controlled dog on the lever for cooperating with the teeth to lock the lever in a plurality of positions.

6. A plow including a beam, a frame secured thereto, a plowshare and moldboard unit pivotally mounted to the frame, a manually operable lever pivotally mounted on the frame, the pivots of said unit and lever being in vertical alignment and substantially parallel, links pivoted to the lever and said unit on opposite sides of the respective pivots.
